I’d like to implement a steep high pass filter around 30hZ or so into the front end of a tube bass amp. Idea is to roll off any subsonic junk for 5 string and protect drivers in a ported cab. Is it as simple as two series passive filters? It Would be cool to make adjustable or at least switchable, but not sure how I would do it with simple passive filters. Thanks for any ideas!
